Summation two cyrillic symbols.

[TyupkinV]

Hello, there was a problem with the application of arithmetic operations to \text {} with Cyrillic. The screenshots show the problem. If you put English characters in \text or or put into another operator
everything works fine. Use in WPF C# .NET 4.5.2

For me, English characters doesn't work inside \text either:

But it's actually a bug, you're right. SystemFont (which is used for \text rendering) is a rather simple class. That's why it doesn't try to determine actual font metrics and just returns whatever System.Windows.Media.FormattedText tells it: https://github.com/ForNeVeR/wpf-math/blob/380507cc15b0d6f1b43cafa98d7d7b360c0ff03c/src/WpfMath/SystemFont.cs#L113-L122

The problem is occurring because even though the Cyrillic symbols are inside "\Text{}", they are considered as SystemFont instead of DefaultTexFont by RowAtom.cs. As a result, the function to GetFontMetrics() inside SystemFont.cs is never called. DefaultTexFont works for the first 256 characters but will fail for any character if a symbol is added afterwards.

By adding a check inside RowAtom.cs for the Element.TextStyle, we actually can avoid the incorrect usage of DefaultTexFont for rendering the Cyrillic characters.

I am sorry, guys, my initial understanding of the problem was wrong. @TheOneAmir, your patch actually fixes the problem, thank you!

Доброго времени суток. Извиняюсь заранее, что на русском, мой английских не сильно хорош, боюсь исказить мысль(думаю не сильно утруднит русский). Да, я хотел бы внести изменения в версию NuGet. И хотел бы задать вопрос, надеюсь на помощь мне в этом вопросе. Хотелось бы лучше освоить C# с помощью вашей библиотеки и попробовать улучшить её, но не знаю с чего начать, не могли бы подсказать с чего начать, потому что я теряюсь в таком большом по моим меркам проекте.

Alright, got it. I'll prepare a NuGet release soon (in the next 48 hours).

Regarding everything else I'll contact you by email.
